plotting a MA style line on a chart that reads its values from a text file

plotting a MA style line on a chart that reads its values from a text file

03-03-2020, 06:38 AM

Hi, I'm new to Ninja Trader, and please excuse my ignorance, but I just cannot seem to be able to find this solution anywhere. I need to plot a moving average style of line onto a chart using values derived from a text file. for example I want to read in consecutive dates and price values from a text file that would have a series of values that have been pre-determined. The line could be straight, sloped or wavy depending on the price values in the text file.

What you want to do would require custom programming in the Ninjascript/ C# programming language.

If you want to create this yourself, we can provide links to references to help get you started but to be clear as small team we do not provide coding or debugging services and are glad to assist if you get stuck on solving a particular question related to ninjascript.

If you want this created for you, we can also provide a link to 3rd party programmers in the NinjaTrader ecosystem that would be glad to provide that service.

In general terms, you would need a script that can read a file and we do have an example of this (linked below), from the data in that file you would need to read in the datetimes and values and then in your script compare the date/time of the current bar in the data series (of the chart you are applying this to) to then "plot" the values you have from the file that relate to that date/time.

NinjaScripts are built on C#. While we do not provide programming education services in the Support Department, there are a vast number of educational C# resources external to NinjaTrader and we do have some tutorials and tools that can assist in the learning process.

Many users report that a good way to start before fully learning C# is to go through the NinjaTrader 7 NinjaScript tutorials in the help documentation to get a fundamental grasp on .NET framework and how it is used in NinjaScript. From there I suggest looking at the Code Breaking changes for NinjaTrader 8 to understand the differences between NinjaTrader 7 and NinjaTrader 8.

Although we do not currently provide NinjaScript tutorials like in NinjaTrader 7, we do provide in-depth help documentation on developing NinjaScripts for NinjaTrader 8. We also provide samples and a complete reference of the language. More in depth educational resources can be found elsewhere throughout the internet.

Once you have a basic understanding of C#, I suggest following the documented Code Breaking changes between NinjaTrader 7 and NinjaTrader 8. This page also gives an overview for NinjaScripts in NinjaTrader 8.

Also available are webinars on the NinjaScript editor and the Strategy Builder. The Strategy Builder can be used to generate NinjaScript syntax for NinjaScript strategies. You may wish to create a strategy and clicking View Code after each piece of logic created in the Builder to observe the generated syntax.
